Summary

Description

We are seeking a Mid-Senior Level Full Stack Developer to support and maintain a suite of existing enterprise applications. This role will focus on stabilizing, upgrading, and maintaining legacy systems that are currently in "keep the lights on" mode.

These applications will eventually be sunset, so the work will primarily involve maintenance, upgrades, and support of existing functionality rather than new product development or greenfield engineering.

The ideal candidate is comfortable working within established systems, addressing technical debt, upgrades, and out-of-support components, and collaborating in an Agile environment.

Key Responsibilities
  • Maintain and support existing enterprise applications
  • Implement system upgrades and updates to ensure applications remain stable and secure
  • Address out-of-support technologies and compatibility changes
  • Troubleshoot and resolve issues in legacy application environments
  • Participate in Agile / SAFe ceremonies, including stand-ups, ticket management, and story refinement
  • Collaborate with development teams to ensure continuity of application functionality
  • Contribute primarily to back-end development, while still supporting full stack functionality as needed

Required Qualifications
  • Mid-Senior level developer experience (not a Lead or Architect role)
  • Strong experience with TypeScript
  • Strong experience with .NET (4.6 - current versions)
  • Experience working with legacy ASP.NET applications
  • Experience with Python (some flexibility; willingness to work in Python environments)
  • Experience working within Agile or SAFe frameworks
  • Ability to maintain and enhance legacy or enterprise systems

Nice to Have
  • Experience modernizing or supporting applications approaching end-of-life
  • Strong debugging and troubleshooting skills in complex environments
  • Experience working on backend-heavy workloads within full stack applications


Requirements

Minimum of 5 years of experience as a mid-to-senior level developer.
Proficient in TypeScript with a strong understanding of its application in development.
Extensive experience with .NET framework, including versions 4.6 and newer.
Familiarity with legacy .NET applications and the ability to work effectively in such environments.
Experience with Python and a willingness to work within Python-based systems.
Strong understanding of Agile or SAFe development frameworks.
Proven ability to maintain and enhance enterprise systems.
Expertise in debugging and troubleshooting complex application environments.
